Answer:
0.0015
Step-by-step explanation:
3/2000
First you do 3/20 which is 0.15 and then you add 2 zeros after the decimal and you get 0.0015
Make x the same in both so
12x+ 4y=72
12x+6y=30
Now the 12x cancel eachother out so
Difference between 6y and 4y is 2y
Difference between 30 and 72 is -42
2y must equal -42
Y = -21
Substitute -21 into the equation
X = 13
